Not only did the elders from across India step forward to help people of Chennai rise back to their feet after being hit by what is considered to be the worst floods in last 100 years, children too actively joined the relief work with whatever they could contribute.

Among several people who have been contributing to some relief to the flood-struck residents of Chennai, there is a group of class 5 students in Tamil Nadu's Coimbatore city who donated some towels and cash for the flood victims.

A group of six students contributed 80 towels and Rs 2,800 for the flood victims in Chennai and Cuddalore.

People from across the nation have been sending relief materials, including food, medicines, clothes, blankets and sanitary napkins, and making donations in the form of cash for the people of flood-hit Chennai, most of whom have been rendered homeless due to flooding.

While thousands of residents of Chennai have been shifted to temporary camps after the torrential rainfall and subsequent flooding submerged their houses, several others are stranded in their homes.

They are all dependent on the relief materials being provided by the government or the people from across the nation, although the rains have stopped and floodwater has receded in many parts of Chennai. The low-lying areas, however, remain submerged.

Some train services and commercial flight operations have been started in the wake of improving weather conditions in Chennai, although there was light rain in Chennai and its suburbs.

Heavy rainfall is expected in the next 24 hours due to twin weather system, including formation of a new trough off Tamil Nadu coast. The India Meteorological Department has predicted heavy to very heavy rainfall in Cuddalore district.

"A trough of low pressure has formed and lies over South West bay off Tamil Nadu coast," a Met official told PTI.

As a result of the two systems, coastal and interior Tamil Nadu and Puducherry will receive rainfall in the next 24-48 hours and some areas like Cuddalore are likely to see heavy to very heavy showers," he said.

In view of the weather forecast, the Tamil Nadu government has declared holidays for schools and colleges in Chennai, Kanchipuram and Tiruvallur.
